To @ZZ whom it may concern.'

Be it lrnown that I, ARTHUR BOBERG, a citizen of the United States, residing at Spokane, in SpolaneCOunty and State of lVashington, have invented certain new and useful Improvements vin Gliders, of whichv capable of free sliding movement on vthe.

floor When movement of the furniture is required, and which is so constructed and arranged that it is capable ofI use with selected sizes of casters. The device is capable of production in' various materials such as hard or close grained Wood, or it may be molded or pressed from composition materials, in colors, sizesv and shapes, adapted to match the style of furniture With which it is to be employed.

By the utilization of the device of myv invention the glider or pad is adapted for selective use With various sizes of casters, and as the gliders are simi-lar in structure and interchangeable, a set of the gliders is readily adapted for Kselective use With various pieces of furniture.

The invention yconsists in a single integral pad or glider having certain novel combinations and arrangements of features adapting it for use in the performance of its functions as will hereinafter be more specifically pointed out and claimed.

In the accompanying dravvingsI have illustrated one complete example o-f the physical embodiment of my invention wherein the parts are combined and arranged in accordance With the best mode I have thus far devisedV for the practical application of the principles of my invention. y

Figure 1 is a perspective view of one of the gliders constructed according to and embodying the principles of my invention.

Figure 2 is a View in vertical cross section of a glider as at line 2 2 of Figure 1. f

at right angles to that of Figure 2 and at lineS-Sfof Figurefl.'`

The glider 1 is a. single integral block hereshovv'n as frusto-conical or ypyramidal in form, but it willfbe understood that the exterior shape of the block` may be changed as desired'to-match or conform with the style of furniture With which the @gliders yaretobe used.' The. glider has a -smooth poiished bottomV face 2,1-:which Will permit ready and free movement over the floor,

Without marring the latter, and has a flat top surface 3 parallel with the bottom.

In the top surface of the block I arrange a pair of diametrically extending and Vintersecting recesses 4 and 5 of rectangular outline'and varying Width to receive and retain a selected caster. The bottoms of these recesses are fashioned with concave arcuate or curved faces 6 and? respectively, the

arcuate curved faces being formed on curved lines of differing radii.` The side Walls 8 of these recesses are perpendicular to the bottom ofthe blocl and they form right angle corners 9 in the top face of the block as shown. v

These recesses vary in depth and Width and are adapted to receive two different sizes of casters as indicated by dotted lines in Figures 2 and 3, Where circles of differing diameters designate the casters.

In addition to the recesses 4 and 5 in the block, other recesses as 10 and 11 are provided by countersinking the respective bottom faces 6 and 7 of the recesses 4 and 5. This second pair of intersecting recesses are of varying Width and depth and their arcuate bottom faces are both of circles of less diameter than the arcuate faces of the recesses 4 and 5.

Thus four of the gliders may be used in a set to support an article of furniture With four legs or feet and casters thereon. The smallest size of caster accommodated is indicated by 'dotted lines at 12 in Figure 3, and this size of caster rests in the recess 10 of each of the four gliders. size caster is indicated by dotted lines 13 in Figure 2 and fits in the recess 11. The succeeding larger size of caster indicated as 14 in Figure 3 may be seated in the recesses 4 of the gliders, and the largest size caster 15 indicated Vin Fig. 2 is accommodated in the recess 5. To adapt the set of gliders to a set of casters of selected size the gliders are turned to the same relative position With The next larger ielation to the seve al casters and the latter are accommodated in the corresponding recesses. The gliders are of siniilar structure and interchangeable and n'hen once located in proper position the casters will loe received and retained therein and the retained caster and glider will partake of the saine movement when the furniture is inoved over the floor or floor covering.

Having thus fully described inv invention, what I claini as new and desire to secure by Letters Patent isl. A glider for furniture comprising a block having a pair of caster receiving intersecting recesses in its upper face with perpendicular' side Walls7 said recesses differing in Width and depth and having concave arcuate bottoni faces on lines of differing radii.

2. A glider comprising a block having a pair of intersecting recesses iu its upper face vdiffering in size and provided with concave arcuate bottom faces, and each said recess having a countersunk recess differing in size from each other and provided With concave arcuate bottoni faces on lines of different radii.

3. A glider' for furniture comprising a block having a pair of intersecting` recesses in its' upper face, said recesses differing in Width and depth and having concave arcuate bottoni faces on lines of differing radii, and each said recess hav' ig a longitudinall7 disposed countersunk recess, the latter' recesses differing in width and depth with respect to each other and provided with concave arcuate bottoni faces of lines of differing radii.

In testimony whereof I afiix iny signature.
